The DHT11 is a digital temperature and humidity sensor. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air and sends out a digital signal on the data pin (no analog input pins needed). Its simple to use, and the update timing of the sensor is about 2 seconds. Thermistor temperature circuits can be much quicker and are very accurate in measuring temperature.
We will be using the DHT11 sensor to measure temperature and humidity. A separate thermistor circuit will also be used to measure temperature on an analog input. This will be all done on our Arduino UNO R3 controller on our super starter kit. Let’s get started.
The servomotor, RC (Hobby) Servo is a type of gear motor that can only rotate 180 degrees. It is controlled by sending electrical pulses from our UNO R3 board. These pulses tell the servo what position it should move to.
We will be wiring the servo to our Arduino UNO R3 controller on our super starter kit. Let’s get started.
We will now look at the tilt ball switch on our Arduino Uno super starter kit. Tilt sensors (tilt ball switch) allow you to detect orientation or inclination. They are small, inexpensive, low-power, and easy to use. Their simplicity makes them popular for toys, gadgets, and appliances. Tilt ball switches are sometimes referred to as “mercury switches”, “tilt switches”, or “rolling ball sensors”.
We will be wiring a tilt ball switch to our Arduino UNO R3 controller on our super starter kit. Let’s get started.
We will now install software to program our arduino uno. This arduino uno software is a free download and will operate on several operating systems. The IDE (Integrated Development Environment) software uses a streamlined version of C++ to write and upload code to the boards. This software is open-sourced and available free of charge. It will run on Windows, Mac, or Linux.
We will be installing the Arduino IDE on a Windows 7 machine. Connecting to our Arduino Uno, we will modify the blink program. (sketch) Let’s get started.
Arduino consists of a family of single programmable circuit boards and the IDE (Integrated Development Environment) that uses a streamlined version of C++ to write and upload code to the boards. Many pre-configured circuit boards, called “shields”, are available to expand the functionality of the Arduino controller. These shields can provide Ethernet, WiFi, GPS, LCD displays, and motor controls, among others, by simply “stacking” or connecting the shields to the Arduino controller board. This Lego-style building of electronic devices is becoming more popular.
The Arduino UNO is one of the best board to learn about electronics and coding. This robust board is the most used and documented board of the whole Arduino family.
We will be looking at the Elegoo Arduino UNO R3 Super Starter Kit. Opening up this great learning tool and discussing the Uno board itself.
Let’s get started.
